Very nice filamental crystal, if it is like pyrite filaments that turn right angle corners. If so this is one crystal with most growth in one dimension - probably due to a screw axis dislocation that makes right angle turns.

Thanks for the information. I received a number of these interesting specimens as a gift from John Cornish.
